Acoustic Imaging for Partial Discharge Detection: Enhancing Electrical Asset Reliability
In industrial and utility settings, electrical failures can lead to costly downtime, equipment damage, and even hazardous conditions. One of the most effective ways to prevent such failures is through early detection of partial discharge (PD), a precursor to insulation breakdown in high-voltage electrical systems. Traditionally, PD detection has relied on techniques such as electromagnetic and infrared imaging, but advances in acoustic imaging technology have introduced a more precise, non-contact method for identifying electrical anomalies. This article explores the benefits of acoustic imaging for partial discharge detection and how it enhances electrical asset reliability. Understanding Partial Discharge and Its Implications Partial discharge is an electrical discharge that occurs within insulation materials or across insulating surfaces when the electric field exceeds the material's dielectric strength. PD can be classified into different types, including: Internal discharge ...
